    Pour un fonctionnement correct et optimal, plusieurs choses sont à prendre en considération.

  • FFmpeg command in Windows to split audio file by silence

    28 January 2019, by ZhouW

    I have previously used ffmpeg to split audio files by silence in Linux, with the following command (taken from How to split video or audio by silent parts, which splits an audio file by silences of -40dB that last at least 0.35 seconds):

    ffmpeg -i testfile.wav -filter_complex "[0:a]silencedetect=n=-40dB:d=0.35[outa]" -map [outa] -f s16le -y /dev/null |& F='-aq 70 -v warning' perl -ne 'INIT { $ss=0; $se=0; } if (/silence_start: (\S+)/) { $ss=$1; $ctr+=1; printf "ffmpeg -nostdin -i testfile.wav -ss %f -t %f $ENV{F} -y %03d.wav\n", $se, ($ss-$se), $ctr; } if (/silence_end: (\S+)/) { $se=$1; } END { printf "ffmpeg -nostdin -i testfile.wav -ss %f $ENV{F} -y %03d.wav\n", $se, $ctr+1; }' | bash -x

    When trying to run this in Windows, I get the following error:

    & was unexpected at this time.

    The above command uses Linux-specific syntax and I’m unclear on how this should be written in a Windows environment. How should this be done?

  • Split a video with ffmpeg, without reencoding, at timestamps given in a txt file

    16 February, by Basj

    Let's say we have a video input.mp4, and a file split.csv containing:

    


    start;end;name
00:00:27.132;00:07:42.422;"Part A.mp4"
00:07:48.400;00:17:17.921;"Part B.mp4"


    


    (or I could format the text file in any other format, but the timestamps must be hh:mm:ss.ddd)

    


    How to split the MP4 into different parts with the given start / end timestamps, and the given filename for each part?

    


    Is it possible directly with ffmpeg, and if not with a Python script?
